    Why would you copy a corvette tune when they already made 6.2 Denali trucks?

    Corvette calibrations are more aggressive and used different parts.

    I wouldn't copy the entire tune either, just the main things you need. Like MAF/VVE data, idle airflow, timing tables. If the injectors are different, change that data.
    2016 Silverado CCSB 5.3/6L80e, not as slow but still heavy.

    If you don't post your tune and logs when you have questions you aren't helping yourself.
